platinum group separation

Separating the Platinum Group Metals by

2019-10-24  It must allow separation of the platinum group metals from the base metals, where the major difference is in complex formation, and also separation of individual platinum group metals from each other, to a high degree of purity. The chloride system provides the most effective operating medium for platinum group metals and is widely used.

Platinum group chemical element group

Virtually all platinum-group metals are recovered from copper or nickel sulfide minerals, which are concentrated by flotation separation. Smelting of the concentrate produces a matte that is leached of copper and nickel sulfides in an autoclave. The solid leach residue contains 15 to 20 percent platinum-group

What Are Platinum Group Metals (PGMs)?

The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

A review of methods of separation of the platinum

2019-8-5  The platinum-group metals (PGM) are technologically important metals which are becoming increasingly relevant in reducing harm to the environment. The separation and purification of the PGM is largely carried out by exploiting differences in the chemistry of their anionic chloro-complexes. These differences include ligand substitution kinetics, ammonium salt solubility, ion-exchange reactions
